At 10 cm cane growth, at stripping and at stoning
The protocol for these trials, as presented to all manufacturers and distributors of liquid products such as Mpact®, was the only top two products that would be fully researched as to their efficiency under agricultural land conditions after glasshouse trials.
Twelve products were tested under these glasshouse conditions grown in sand medium containing no humus. All required nutrients for grass growth were applied plus the products at dilutions as per label instructions.
The research data from these trials are in the graphs above. The results indicate that Mpact® is one of the two products to give positive results.
